Desolation Sound, British Columbia, and adjacent inlets (Malaspina, Okeover, Lancelot, Theodosia) included in the study area. search the surface of the water. Birds seen in the spotlight were approached stealthily, as closely as possible, and scooped from the surface of the water with a salmon landing net. This close approach allowed identification of birds not captured. Results A total of 337 nights on the water, averaging 6 hours per night, and 58 daytime at-sea surveys were conducted during the four study summers (Table 1). During these four years, we captured 1184 Marbled Murrelets and sighted 14 161 more on at-sea surveys (Centre for Wildlife Ecology, Simon Fraser University, unpublished data). Although not quanti- fied here, Pigeon Guillemots (Cepphus columba) were somewhat common in the area, with a few pairs observed in Malaspina Inlet every year during at-sea surveys, and some breeding near the study area on Mitlenatch Island. We made seven observations of three alcid species rare to the study area (Table 2): Table 1.

One Parakeet Auklet was captured on 13 March 1998, measured, pho- tographed, but not banded. (2) Ancient Murrelets. One Ancient Murrelet was captured during a dipnet session on 6 August 1999, caught, banded, measured, and photographed (band and photograph available on request). One Ancient Murrelet was seen during a dipnet session on 20 July 2000. Neither Ancient Murrelet had plumage characteristics of breeding adults, and thus, were suspected juveniles or non-breeders.
